Background technology
The photovoltaic component terminal box of main flow in the market, mostly is the combining form of box body and lid, and is provided with the electric component such as busbar, diode in box body.Along with the appearance of intelligent assembly, the content of photovoltaic component terminal box obtains substantial, because the intervention of control circuit; Meanwhile, form also there occurs change.Considering the possibility of electronic failure, in order to ensure photovoltaic module overall 25 year life-span, when smart electronics component malfunction, needing to change it in time.Therefore, the electronic unit of easy inefficacy is integrated into (traditional is be assembled in box body) on lid, now then need the electronic unit in lid to be connected with the busbar in box body, with the normal work of the electric energy output and smart circuit that realize photovoltaic module.
Fig. 1 shows syndeton of the prior art, as shown in the figure, is integrated in stitch (1) on lid when being inserted in socket (2), due to: 1. socket outlet size is certain, requiring that stitch position is comparatively accurate, as there is position deviation, then causing lid cannot coordinate with box body; 2. in socket, slot width is greater than stitch thickness, and after insertion, stitch and female contact are abundant not, while increasing contact resistance, and can not the abundant transmission of guarantee information.
We know, the development trend of photovoltaic module reduces the series resistance of assembly, thus the lifting of implementation efficiency, and the increase of contact resistance, will the effort of assembly battery-end improved efficiency be caused to be thrown into the eastward flowing stream undoubtedly.
Summary of the invention
The technical problem that installation is inconvenient, contact resistance is large that the utility model exists for photovoltaic component terminal box in prior art, there is provided a kind of for the electrical connection arrangement in photovoltaic component terminal box, reduce contact resistance and make the installation of terminal box become more convenient.
For this reason, the utility model adopts following technical scheme:
A kind of for the electrical connection arrangement in photovoltaic component terminal box, comprise the stitch be integrated on lid and the socket shell fragment be arranged on box body, described stitch can insert in socket shell fragment and form electrical connection, it is characterized in that: described socket shell fragment comprises the first holding piece and the second holding piece, the tail end of the first holding piece and the second holding piece is connected to form installation portion, socket shell fragment is connected on box body by this installation portion, second holding piece comprises from tail end successively to head end: for the kink be connected with the first holding piece, vertical component effect, the first outward-dipping guide part and the second guide part of level, the clamping part that can clamp stitch is formed between the vertical component effect of the first holding piece and the second holding piece.The utility model by designing the first and second guide parts on socket shell fragment, when position stitch devious is inserted, can automatic guide, solve the problem cannot inserted because stitch dislocation; , designed by the shell fragment of suitable dimension meanwhile, can contact more fully with socket shell fragment after stitch is inserted, reduce contact resistance, thus optimize the overall performance of photovoltaic module.
Further, the length of described stitch is suitable with the length of the first holding piece, and the length of clamping part is 2/5 ~ 3/5 of leg length.Stitch can contact with socket shell fragment after inserting more fully, reduces contact resistance, thus optimizes the overall performance of photovoltaic module.
Further, described installation portion has flat bottom.Be convenient to the installation of socket shell fragment in box body.
Further, the width of described installation portion is greater than the distance between the first holding piece outer surface and the vertical component effect outer surface of the second holding piece.Be convenient to the installation of socket shell fragment in box body.
Further, the width of described clamping part is slightly less than the thickness of stitch.Make stitch more tight, firm in the connection of clamping part.
Further, the angle of the length direction of described first guide part and clamping part is 15-25 °.There is the longer better guide effect of guiding Distance geometry.
To sum up, the utility model can contact resistance effectively in terminal box between stitch and socket, meanwhile, makes the installation of terminal box and replacing become more convenient.
